Core shaft puller

A portable shaft puller comprising an elongate housing having vertically disposed laterally spaced apart side walls,

• a saddle having vertically disposed crosswise extending front walls formed with a recessed portion extending downwardly from the upper edge dimensioned to enable a portion of the shaft to be received therein,
• means mounting the saddle above the side walls of the housing for movement of the saddle lengthwise of the housing between forward and rearward positions of adjustment,
• driving means within the housing comprising a reversible air motor,
• an operative connection between the driving means and the saddle for displacement of the saddle between forward and rearward positions of adjustment,
• a clamping means rigid with the housing forwardly of the forward position of adjustment of the saddle for releasably clamping a core thereby to restrain the core during insertion or withdrawal of the shaft,
• fixed support means between the clamping means and the forward position of adjustment of the saddle for support of portions of the shaft forwardly of said forward position of adjustment,
• means for moving the housing over a horizontal surface for positioning the saddle in vertical alignment with the shaft to be withdrawn or in alignment with the core into which a shaft is to be inserted,
• and air pressure operated lift means for raising and lowering the housing.
